Patent CA-2289185-A1 (CA)
Inventor: SENYSHYN PAUL ANDREW
IPC: H04L12/413
Filed: 1999-11-09
Abstract: A node on a collision detection protocol based network forces collisions to gain control of the network when it has real time data that needs to be transferred to another node on the network, and then begins transmitting the real time data prior to other nodes gaining control of the network. Each node which has real time data to transfer keeps track of a maximum wait time parameter to determine when the real time data must be transferred to ensure it arrives at a destination on time. As the maximum wait time is approached, the node forces a collision by transmitting even though it senses another node is already transmitting to force the network into a quiet mode. It then starts transmitting the real time data prior to other nodes beginning transmission.

Patent CA-2297896-A1 (CA)
Title: Method of controlling communication resources
Inventor: RINNE MIKKO J
IPC: H04L12/56
Filed: 1998-07-31
Abstract: According to the method of the invention, connections are divided into at least two different connection classes according to their requirements for transmission delay. The control system of the base station subsystem maintains a record of the transmission needs of the users logged in different categories and based thereon divides the available radio resources into slots of suitable capacity. For connections with stringent requirements for transmission delay, circuit-switched connections are allocated with a bandwidth which can be controlled dynamically.       Then from the resource pool still unassigned after the resource allocation to the circuit-switched connections, a sufficient amount of resources are allocated on a time-limited basis allocation for each allocation period to connections having a higher tolerance for delay so as to accomplish transmission, e.g. of a given amount of data.

Inventor: SHPIEGL ETAI
IPC: A01H5/10
Filed: 1998-07-26
Abstract: The present invention discloses genetically engineered plants which display altered structure or morphology. The transgenic plants express a cell wall modulation transgene or gene construct that results in the altered structure or morphology. The altered structure or morphology can be associated with, for example, altered biomass, growth, yield, greater or less resistance to biodegradation, more or less digestible to ruminants, altered cellulose content, larger leaves/normal hypocotyls or smaller leaves/longer hypocotyls, etc. compared to a non-transgenic plant of the same species. The cell wall modulation transgene can be any cellulose binding domain, a cellulose binding protein, or a cell wall modifying protein or enzyme such as endoxyloglucan transferase, xyloglucan endo-transglycosylase, an expansin, cellulose synthase, or a novel isolated endo-1,4-.beta.-glucanase of Arabidopsis thaliana. The invention also discloses transgenic plants containing a gene construct comprising a promoter operably linked to the cell wall modulation protein or polypeptide gene and may further comprise a sequence encoding a secretion signal peptide. In particular, the invention discloses transgenic plants containing a gene construct comprising the cell promoter, operably linked to the cell signal peptide and any cellulose binding domain.

Abstract: Self-enclosing heat exchangers are made from stacked plates having raised peripheral flanges on one side of the plates and continuous peripheral ridges on the other side of the plates, so that when the plates are put together, fully enclosed alternating flow channels are provided between the plates. The plates have raised bosses defining fluid ports that line-up in the stacked plates to form manifolds for the flow of heat exchange fluids through alternate plates. Rib and groove barriers are formed in the plates inside the peripheral flanges and ridges. The barriers prevent short circuit flow on one side of the plates and promote flow to remote areas on the other side of the plates, to improve the overall efficiency of the heat exchangers.
Patent CA-2298736-A1 (CA)
Inventor: OCHI HIROTOMO
IPC: G01N33/50
Filed: 1998-05-29
Abstract: A diagnostic plot derived from the measurement of 82 assays which characterize two key parameters which significantly contribute to an individual's health status. These two parameters are oxidative stress profile (OSP) and antioxidant profile. Each of the assays which constitute the 82 assays are complimentary with other assays of the profile, thus providing either confirmation information or the synthesis of new information. The diagnostic plot, developed to interpret the assay data which provides information about oxidative damage and antioxidant protection, consists of four quadrants, each with noticeable characteristics. By visually assessing the position of a patient's OSP status, in comparison to reference OSP values in the four quadrants constituting the diagnostic plot, physicians and other health care professionals can provide sound advice to their patients regarding dietary and life style changes one need to adhere for prevention of oxidative stress-related diseases as well as postponing premature aging processes.

Patent CA-2299771-A1 (CA)
Inventor: SALVARANI ALEXANDRO FEDERICO
IPC: H04B7/26
Filed: 2000-02-28
Abstract: A method of controlling the power in a wireless communication system (200). In one embodiment of the invention, a base station (210) determines the information rate of a signal to be transmitted (270) to a mobile station (220), and obtains the variable power control scaling factor (245) based on this information rate. The base station (210) then transmits the variable power control scaling factor (245) to the mobile station (220). The mobile station (220) determines a target signal quality measurement (130) for a received signal (270) from the base station (220), such as a target E b/N0 (130), and scales the target E b/N0 (130) by the variable power control scaling factor (245). The mobile station (220) also obtains an information rate scaling factor based on the information rate of the received signal (270), and further scales the target E b/N0 by this information rate scaling factor. The mobile station (220) then compares the target E b/N0 (130) to a measured E b/N0 (160) of the received signal (270). An increase in power of the received signal (270) is requested when the measured E b/N0 (160) of the received signal (270) is smaller than the scaled E b/N0 (260). A decrease in power of the received signal (270) is requested when the measured E b/N0 (160) of the received signal (270) is larger than the scaled E b/N0 (260). Providing the variable power control scaling factor (245) to the mobile station (220) allows frames having an information rate lower than the full rate to be transmitted at a power even lower than the power of a frame having an information rate equal to the full rate times the information scaling factor.
